Even though the web is filled with these kind of posts, the main reason i’m [kinda re-]posting is that I actually got better battery life after following some specific instructions, and turned off some apple surveillance along the way. I’ll do my best to describe what the setting changes actually mean, but most of these are either poorly documented or not documented at all. Also, some guides around the web seemed to me a little misguiding, asking users to make changes that in my opinion will make the experience suffer without a major increase in battery performance.
Well, here goes nothing:
- Turn off System Services that use Location Services. This includes lots of very ‘useful’ stuff such as location based iAds (yey!). To find these go to: ‘Settings’ -> ‘Privacy’ -> ‘Location Services’ -> Scroll down until you reach the bottom, then choose ‘System Services’. I Took the liberty of turning them all off and I can’t say there’s been any noticeable functionality difference.
- Turn off Background App Refresh. An app listed here will wake up every now and then to catch up on recent server changes. Chances are, though, it will do the exact same thing once you open it. If you care so dearly for that few seconds improvement in launch speed, go right ahead. Personally, i’m positive not many software vendors even got the chance to add this feature and optimise it, so i just turned it entirely off. You do this by going to: ‘Settings’ -> ‘General’ -> ‘Background App Refresh’. If there’s a specific app you use very often and want this feature enabled for, you should selectively enable Background App Refresh for that app. I’m just assuming most users will want their facebook timeline updated in the background, whatever implications it may have on their phones’ battery lives.
- Turn on Reduced Motion. This ‘accessibility’ feature ‘reduces motion’ in the OS. I Have to say that having it disabled for about two days now, i haven’t noticed any difference. The word on the street says it turns off some parallax effects and such, not much of a give-up for me anyway. Go to ‘Settings’ -> ‘Accessibility’ -> ‘Reduce Motion’ and turn it off.
What you shouldn’t do:
- Do not turn off automatic downloads for app updates. You can set this feature to only work on WiFi or just stop worrying: iOS doesn’t check the app store for app updates every 5 minutes, but rather a lot less often than that. Even if they did: opening an app and seeing a new feature or a fresh look (especially in this season of iOS 7 redesign) is really neat, and not having to manually update each time a bug is fixed in that alarm clock app you downloaded a year ago is even neater. Keep it on.
I Guess no one is entirely sure what causes the new OS version to be noticeably more power consuming than the previous one. Some people say apple will patch to try and remedy some of the worsening, but I wouldn’t count on them targeting optimisation at this point, they have lots of urgent stuff to do. Judging by my own experience, following along the aforementioned steps does improve battery life on iOS 7.0, and is probably the best thing you can do right now to achieve that.Wish you all mobile longevity,
